, Specification of Letters intent. Application filed September 30. 1910.Serial No. 584,679.

TO EUGENE Patented Dec. 5, 1911.

To all whom it may concern:

' Be it known that I, FRANK S. HARRING- TON, a citizen of the UnitedStates, residing in the city of Bridgeport, county of Fairfield, andState of Connecticut, have invented certain new and useful Improvementsin Picks; and I do declare the fol lowing to be a full, clear, and exactdescrip tains'to make and use the same.

' .My invention relates to certain new and useful improvements in picks,but more'particularly has reference to the manufacture of a device ofthis description in sections so that when a part becomes broken or worna an elevation showing the parts.of my im-.'

provement assembled with one of the eye sections removed Fig. 3 asection at the line a m, of Fig. 1 Fi .4 a detail enlarged view 'of theinterior 0 one of .the eye sections, and Fig. 5 a view. similar to Fig.2 but showing the parts of my improvement assembled in a sli htlydifferent manner such as wouldbe suitable in the instance of a straightpick.

Similar numerals of reference denote like parts in the several figuresof the drawing. 1 are the eye sections which have formed integraltherewith curved portions 2 that are complementary of the eye, andinteriorof each of these sections and on opposite sides of the portions2 are wedge shaped o positely disposed recesses 3 WhlCh are per 0- orthe purpose presently to be explained.

5 are the pick points of any suitable and approved shape, the heel endsof which are wedge shaped and provided with elongated slots 6.

In the usual form of pick, such as iscommonly used, the pick omtsslope'toward the inner end of the ban 1e 7 as shown at Figs.

1 and 2, and in the present instance this is brought about by merelyassembling the eye sections 1 and points 5 as is shown particularly atFig. 2, wherein the inclined walls of the recesses 3 are nearest theinner end of the handle 7, but in case a straight plck is desired, suchas iscommonly used 1n coal mlnes, the parts would be assembled as isshown at Fig. 5, wherein the inclined end of the pick.

walls of the recesses 3 are nearest the outer In assembling the parts ofmy improvement, the wedge shaped heel ends of the pick points are forcedwithin the recesses 3,

and the sections 1 are clamped firmly against these heel ends bymeans ofbolts 8-- passed through the perforations 4 and slots 6, these boltshaving threaded outer ends which preferablyengage withthe threaded wallsof the perforations 4 in one of the sections 1, nuts 9 being threaded onthe extremitles of these bolts for the purpose of ,clamping the sections1 against said heel ends, the thickness of the latter. being slightlygreater than the combined de th of the recesses which contain them, so tat the sections 1 may be firmly clamped against said ends.

Thehandle 7 is driven within the eye formed by the curved portions 2 inthe usual manner. v

In Fig. 5, the handle eye is tapered oppositely from that shown in theother form of the invention, necessitating the use of" a handle ofspecial form,

Constant use of the pick will'causethe heel ends to be driven morefirmly within the'recesses 3, and this will be accomplished without theslightest shock against the bolts 8 owingto the fact that the latterextend freely through the elongated slots 6 in these heel ends, and thisis a very important feature since ifthe' shock occasioned by the use ofthe pick is sustained either by the bolts or by any part having contactwith the latter, these bolts are very apt to become bent or brokenandthe pickitself thereby rendered useless.

In my improvement, the pick points, in

the event of breakage or undue wear, are

readil replaced by new points, and the same is true of the eye8801510118.

Variouskinds of points may be utlllzed in connection with my improvementso that the latter may be employed as amattock,

a millstone hammer, a mill pick, &c., and my invention is therefore notlimited in this respect so long as the points are provided with thewedge shaped heel ends. 7

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is A pick h'ead composed of a pair of similarsections, each having a central transverse curved portion conjointlyforming a handle receiving eye, and with further having a wedge-shapedrecess on each side of the curved portion thereof communicating with thelatter and extending through the end of said sections, pick pomts havingwedgeshaped heels received in said recesses, and formed withlongitudinal slots, bolts passed through the sections and extendingthrough said slots, said slots being of considerably greater length thanthe diameter of the bolt and being arranged so that the bolts extendadjacent the inner end of the slot, to thereby permit the pick points tohave an inward movement with respect to the bolts, the inner ends ofsaid wed e-shaped recesses being each closed by the andle, the handleextending inthe eye formed by said sections.

In testimon whereof I aflix my signature in presence 0 two witnesses.

FRANK S. HARRINGTON.
